Dr. Julia Lewis and EEG Analysis
Just like the rhythm of the heart beat signals can be seen in an EKG (electrocardiogram) – the brain gives off faint signals than can be seen as waveform patterns in an EEG (electroencephalogram).
Everyone’s brain wave patterns are unique like their finger prints. However, when we are injured these unique patterns change and begin to look the same. Due to injuries, disease, or chemical toxicity the brain misfires, creating abnormal waveform activity that can be faster/slower frequency and/or higher/lower voltage than what is considered “normal”.
Toxins like anesthesia and antibiotics affect the brain, causing issues with memory and cognitive impairments like difficulty with spatial ability to judge distances or do computations. Prolonged anesthesia exposures like heart bypass surgery can cause brain fog or “pump head” – the mild cognitive decline many have reported experiencing after their bypass surgery.
This is what a normal adult EEG looks like on the Neuropathways equipment (1) developed by Dr. Margaret Ayers, PhD. That Dr. Lewis uses in her office.This EEG has no evidence of damage or disease.The FIRST line is the real-time raw EEG showing all frequencies from zero to 450 HZ.The SECOND line, A , is 15-18 Hz beta activity, the frequency that contains the functional energy.The THIRD line, B, is 4-7 Hz theta where slowing from damage or disease are found. – ©Ayers/Montgomery 2004
The brain has distinctive brain wave patterns that can be seen in a real time displayed EEG. By placing small gold-plated leads on the scalp with conductive paste it is possible to see these rhythmic patterns with Dr. Lewis’ sensitive equipment.
The EEG brain waveform evaluation shows if the areas measured are running primarily in the normal range or if the brain is misfiring either fast or slow. A brain that speeds up is an indicator that the brain has more energy available to heal. Most often the brainwave activity is faster in people experiencing allergies or mild cognitive decline due to toxicity.I PATTERN 19-22HzSeen when the immune system is challenged, observed in frontal lobe.Third line of data is 20-25Hz – ©Ayers/Montgomery 2004
The burst activity in the bottom row in the graph above shows the fast activity present in the top row which shows all activity in 0 to 25 Hz range. The I pattern refers to the Immune System. This person has trouble focusing their attention because of the bursts of fast activity.22 year-old with a head injury due to an automobile accidentSite is T4C4 – ©Ayers/Montgomery 2004
Head injuries don’t all look the same. But what they do have in common is increased slow wave activity present in the 3rd or bottom row on each page. There are bursts of slow wave activity present in the graph above and below.CLOSED HEAD INJURY – spikes are easy to see in this example – ©Ayers/Montgomery 2004 ATTENTION DEFICIT HYPERACTIVITY DISORDERF4T4.

ADHD presents with excessive slow wave activity. These individuals fidget a lot because they are trying to speed up their brains. The typically respond well to Ritalin because it speeds up their brain. It is possible to train this kind of brain to speed up on its own with proper Neurofeedback training.
It is also possible to analyze the brain for other conditions like head injury, concussions, allergy, ADHD, stroke, insomnia, as well as stress urinary incontinence. This analysis requires measuring the brainwave activity based on the location of trauma and the part of the brain that controls the area related to the symptoms.
The Neuropathways equipment also has a training capability to help the brain to create new healthy pathways so it can start firing more properly again. This training is called Neurofeedback. (1)
